WHETNEY, Ephraim, s. Moses and Sarah, [died] May 4, 1723.
↑ Relying on Source:Whitney Research Group (WRG), here, there is apparently such an absence of clues that they cannot even estimate an approximate birth. He would easily fit in the 1690s, or after Lemuel in 1706 (Lemuel is called the youngest son on a date that is after the death of Ephraim). It may also be possible, since purported sibling Abraham and wife Mary have a son Ephraim b. Apr 1723 who "d. young", that the parents were misrecorded and this death date applies to their son, being a couple of weeks old on the date of this death record?
